摘要： An expandable reamer includes a shank portion, a cutting portion extending from the shank portion, and a tapered pin capable of being at least partially received in the cutting portion. The cutting portion includes a plurality of blades separated by flutes, and a tapered inner surface with threads. The tapered pin includes a tapered outer surface with threads and causes expansion or contraction of the cutting portion when the tapered pin is screwed or unscrewed into the cutting portion. In one embodiment, a coolant channel extends from a coolant cavity through a wall of the cutting portion to provide fluid to the blades during machining of through-holes. In another embodiment, the tapered pin includes a coolant passage in fluid communication with the coolant cavity to provide fluid to the blades during machining of blind holes.
摘要翻译：可扩展铰刀包括柄部，从柄部延伸的切割部分和能够至少部分地接收在切割部分中的锥形销。切割部分包括由槽纹分隔开的多个叶片以及具有螺纹的锥形内表面。锥形销包括具有螺纹的锥形外表面，并且当锥形销螺纹拧入切割部分时，导致切割部分的膨胀或收缩。在一个实施例中，冷却剂通道从冷却剂腔延伸通过切割部分的壁，以在加工通孔期间向叶片提供流体。在另一个实施例中，锥形销包括与冷却剂腔流体连通的冷却剂通道，以在盲孔加工期间向叶片提供流体。
